A high pass filter pad is provided to detect and check a noise inflow point correctly and rapidly without stopping a service for a long time. A high pass filter pad includes a high pass filter. The high pass filter of 19MHz is embedded in a pad mounted inside an amplifier. The high pass filter of 19MHz is designed for a radio frequency signal power level not to be distorted, and to maintain a conventional attenuation value. If an uplink frequency band signal of 5-54MHz is inputted from a first pine, a signal of 19MHz band is suppressed through a filter. An internet service signal of 20-54MHz band is outputted to a second pin. |
